TELEPHONE INSTRUMENT AppLication filed August 20, 1925. Serial No. 51,385.

This invention relates, generally, to improvements' in telephones; and, the present invention has reference, more particularly, to a novel receiver element for' telephones,

the relation of the said receiver element to the standard or post of the telephone being such, that a pivotal arra'ngementof there'- ceiver element in one position will interrupt the electrical current used with the telephone, but when in another position, in'oth er Words, the receiving position, will complete the electric circuit, and at the same time said receiver element is maintained in its raised or hearing position at the ear or cars of the person at the instrument, without the neces sity of the person having to hold the soundreceiving element in place before the ear.

The invention, therefore, has for'its prin cipal object, to provide the. standard or post of a telephone. and the circuit-making and interrupting means thereof, with a movable or pivoted frame or device, carrying receiving means, which when raised will establish the usual electrical circuit, and when in its fully raised position will remain in such position without any further effort and holding of the device on the part of the user of the telephone, so that the person'at the desk has the free use of both hands for other pur poses, and still, without any inconvenience, being able to use the telephone for the usual talking and hearing purposes.

Other objects of the present invention not at this time more particularly enumerated will be more fully understood from the following detailed description of the present invention 'ith the various objects of the invention in vicw. the invention consists. primarily. in the novel tclephone-instrument hereiir after more fully set forth; and. the invention consists. furtln-rinore. in the novel arrangements and combinations of the various d vices and parts. as well as in the (l(l2lll. of the construction of the said parts. all of which will he more fully described in the following specification. and then tinally cur hodied iii the clauses ol' the claims. which are uppctulcd to and which form an essential part of the said specification.

The invention is illustrated in the accompanying drawings. in which .Figure 1 is a side-elcvation of a telephone instrument provided with a self-sustaining sound-receiving element made according to" and showing one embodiment of'theprin ciples of the present invention; Figure 2 is a front view of the'same; Figure 3 is a v iew showing partly in 'plan' andpartly ili hori zontal section, portions of the frame-min s) bers and their pivotal connectiorr'vi itlfthe" standard or post of the telephone-of the aid sound-receiving element; and Fi'gii'res' i i 6 and 7 are detail views of certain members of the pivotal connection of the device.

Figure 8 is a view. similar to Fi ure-1'; showing a slight modification ofthein vntion; and Figure 9 is a perspective' view, illustrating a fragmentaryporti'on of the standard or post of a telephone-instrument, and showing in connection therewith,a circuit-making and breaking means used with the arrangement of devices as illustrated in said Figure 8.

Similar characters of reference are employed in the said above describedviews, to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-character 1 indicates a usual form of telephone standard or post which is hollow or tubular, and which 'contains the usual electrical means used with telephones. In its side,'t-he said standard or post has an opening, as Q, in whichis' movably disposed an oscillatory and spring -co ntrolled, or other suitably actuated make and break-establishing element 3, as indicatedin' Figures 1 and 2 of the drawings, on'whi'ch may be a vertically slidable element, as4, as indicated in Figures 8 and 9; The upper end-portion of the standard or post 1. is bifurcated. as at 5 and 6. between whiclris pivotally arranged. in a manner to be presently described. a rearwardly extending pon tion 8 of the usual transmitter 7 into which is screwed any usual construction of mouthpiece 9.

The herein-hefore mentioned receiving means of the telephoneinstrument consists. essentially. of a pair of suitably-shaped 'tiuhular arms. as and 23. said arms carrying upon their outer end-portions 24, suitable receivers 25, in communication with thefhollow portions of said arms, and electrically connected with the circuit-wires 26, leading into and through said arms, as a t'QT. Re-

(ill

ferring now more particularly to Figure 3 of the drawings, it will be seen that the said arms 22 and 23 are suit-ably curved, as at 28 and 29, said curved portions being provided with hubs or bearing-portions 30 and 31. Upon their inner flat faces 32, the said hubs or hearing-portions are made with radially extending depressions or grooves, as 33. Extending from the hub 30 of the arm 22 is an are or other suitably shaped mem ber 3 1, terminating at its free end in a fiat end portion 35, and similarly extending from the hub 31 of the arm 23 is an arc or other suitably shaped member 36. terminating at its free end in a flat end-portion 37, located so as to be placed directly beneath the flat end-portion 35, shown in said Figure 3, and for the purposes to be presently more fully set forth. Suitably disposed in the hub 30 is a stem 38 having a collar 39 provided with a rib 40, adapted to be brought into retaining engagement with either of the depressions or grooves of said hub.- Extending from said collar 39 is an angularly bent shank 41 which is screwthreaded, as at 42, and has a non-threaded shank-portion a3, provided with a stud it. At its opposite end, the stem 38 has extend ing therefrom a screw-threaded stem-pen tion 45, upon which is an adjusting nut l6 and a coil-spring 47. In like manner, there is suitably disposed in the hub 31, a stem 48 having a collar 49 provided with a rib 50 which is adapted to be brought into retaining engagement with either of the depressions of the said hub. Extending from said collar 49 is an angularly bent shank 51. which is screw-threaded, as at 52, and has a non-threaded shank-portion 53, provided with a screwthreaded socket 54, into which the stud 44 extends, as shown in said Figure 3 of the drawings. At its opposite end, the stem 48 has extending therefrom a screwthreaded stem-portion 55, upon which is an adjusting nut 50 and a coil-sprin 5T.

Lock-nuts 58 and 59 are screwed upon the screw-threaded portions l2 and so as to properly maintain fixed relations ot' the shank-portions 43 and 53 in the members I and 6 of the standards or post 1. and also in the tubular portion 8 of the transmitter T.

Suitably connected with the outer end portions 2 1 of the arms 2'3 and J3, and ha ing communication with the interior of said tubular arms, are suitably constructed re ceivers 25.

The manner of raising either one or both of said arms 22 and for hearing purposes will be fully understood from an inspection of Figures 1. 2 and 3 of the drawings. the raised arm or arms remaining in raised position, with the receiver or receivers against the ear or ears of the user of the telephone. without necessitating any further use of the hands for holding the device against the. car, as with the usual style of telephone. Thus, while talking and listening, the operator has the free use of the hands for other purposes without interrupting conversation over the telephone. When the arms 22 and 23 are lowered, the element 3 is moved in a downward direction, so as to shut ott the electric current, as will be evident.

If desired, the contact making and breaking element 4, see Figure 9, may be provided with a hook, as 68, against which the lowered arm is adapted to be moved so as to'depr ess the element 4, and thereby shut off the elec' tric current.

Of course, it will be understood, that anv other suitable style and construction of COIitactmaking and breaking means may be employed. I

From an inspection of Figure 3 it will be seen, that when the arm 22 is raised, the portion 35 moves out of contact with the portion 37, thus enabling this arm to be used for bearing purposes, with the arm 23 remaining in its lowered and inactive position. thus permitting the use of but one receiver. However, when it is desired to use both receivers, then the arm 23 is raised, the move ment of the portion 37 against the portion 35, also causing the arm 22 to be raised into the desired position.

I am also aware, that other changes may be made in the general arrangements and combinations of the various devices and parts, as well as in the details of the construction of the said iarts without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses of the claims, which are appended thereto. Hence, I do not limit my present invention to the exact arrangements and combinations of the various (le vices and parts. as described in the foregoing specification. nor do I confine myself to the exact details of the coi'istruction of the said parts as; illustrated in the m- 'oiiip-.:ii in; drawings.
